How to work with schmidt hammer | ||
1 | Hardness testing of materials schmidt hammerUse a grinding stone to smoothen the test surface | |
2 | Perform a few test impacts with the rebound hammer on this smooth, hard surface before taking any measurements which you are going to evaluate. Perform a consistency check on the test anvil | |
3 | Position the hammer perpendicular to and against the test surface. Push the concrete test hammer adainst the surface at a moderate spped until the impact is triggered. Bes aware that the plunger generates a recoil when it deploys. |
The concrete rebound hammer are the most widely used portable NDT measuring instruments for a rapid assessment of the condition of a concrete structure
TEM912&TEM91 Series DIGITAL TEST HAMMER automatically Record, Save, Calculate and Processing data.
ZC3-A Concrete Rebound Hammer , in accordance with JGJ/T23-2001 technical regulations, is used for detecting the concrete compressive strength within the range of 10-60Mpa and has the system standard energy of 2.207J
